This Sans is from my ExperimenTale AU,
"It's where Sans continued his scientific career & became co-workers with Alphys. Mostly their story is much more apparent in a Genocide Route 'cause I actually didnt thought one with the Pacifist Route.
In a Genocide Route, everyone gets killed & such. And of course, Papy gets killed. But instead of battling the human. Sans tries to resurrect his brother by use of DETERMINATION.(Since he & Alphys knew what happened to Asriel after he became Flowey). He made an exact skeleton replica of his brother, extracted the remaining dust essence from Papy's scarf then injected it with DETERMINATION(kinda like a Frankenstein thing). He did succeed to bring Papyrus back to life only to realize that Papy's not what he used to be. He cant feel emotions or feelings as it did to Flowey. And as the Human gave up on the world, Papyrus' DETERMINATION took over and he's capable of resetting time. So yeah, his experiences are the same with Flowey"
And to clarify, he's not Sci...i mean yeah technically but no, they're from different timelines, different aus
The prompt was for him to pull up a photo of fell sans
funny thing is, his au has never open to the multiverse and so had never met alternates canonly
